The aluminium litzendraht wire butt welding mechanism is before use, the quantity of the chain 4 is one, first by one end of the chain 4 54 caught on by the second hook, the other end of rear chain 4 caught on by the first hook 11 around after one of sprocket wheel 36.
The aluminium litzendraht wire butt welding mechanism can be used for the weld job of aluminium litzendraht wire or aluminium litzendraht wire single line in wiring, Concrete operations are as follows:
1), more wiring cards to be welded enter to cable clamping interface 611, the wiring to be welded be aluminium litzendraht wire or aluminium litzendraht wire singly Line;Then by the wiring to be welded in first card line device 6 respectively with the wiring to be welded in second card line device 6 in lower conduction It is docked one by one at the upper end of column 22;The presence of cable clamping interface 611 advantageously allows wiring to be welded in first card line device 6 and the Centering is completed in wiring to be welded in two card line devices 6;Then the plate 621 in iron covering plate 62 is inserted into cable clamping interface 611.It gives Electromagnet 63 is powered, and electromagnet 63 is located at the slot bottom of holding tank, and the bottom of bottom plate 61 is located in holding tank, and bottom plate 61 is received Slot, which limits, will not shift or misplace, and then under the absorption of electromagnet 63, iron covering plate 62 can be along plate 621 and card The restriction direction of wire casing 611 moves downward, so that plate 621 can tightly suppress the wiring to be welded in cable clamping interface 611, avoids Wiring to be welded misplaces.Wherein, cable clamping interface 611, further, the plate 621 and cable clamping interface are inserted into for ease of plate 621 It is clearance fit between 611.Further, lift iron covering plate 62 for convenience, the top of the iron covering plate 62 is installed with T shape handles 622.Since the side wall of wiring to be welded is cambered surface, further, the slot bottom of the cable clamping interface 611 is cambered surface.This makes to be welded Line is not easy when being squeezed by plate 621 by " flattening " so that the shape of wiring to be welded is not easily damaged.Card line in the bottom plate 61 Plate 621 in slot 611 and iron covering plate 62 can according to the different designs of the cross-sectional area of wiring to be welded at more covering devices, due to All bottom plates 61 can be located in holding tank, then adsorb iron covering plate 62 by wiring to be welded to pressing using electromagnet 63 Firmly, to avoid wiring to be welded that dislocation or offset occurs.
2), staff hand hold handle 32, then above carry so that first connecting rod 31 can be 33 turns around supporting table Dynamic, under the drive of first connecting rod 31, upper conductive column 21 can also move upwards so that above between conductive column 21 and lower conductive column 22 There are larger gaps, as shown in Figure 3.And sprocket wheel 36 is rotatablely connected with wheel shaft 35, the sprocket wheel 36 can be around wheel shaft 35 Rotation, under the cooperation transmission of sprocket wheel 36 and chain 4, the second hook 54 also moves upwards therewith, and the second hook 54 also can be same Step drives second connecting rod 51 to be rotated around third connecting rod 53.
3), since the end of all wiring to be welded is all placed on the upper end of lower conductive column 22, then holding handle 32 makes it It moves downward until the lower end of upper conductive column 21 can be pressed in the end of wiring to be welded, is pressed downward handle 32 with strength again at this time, this When first connecting rod 31 be equivalent to one " lever ", can to upper conductive column 21 apply pressure so that wiring to be welded end It portion can be by normal pressure.At the same time, staff can will ride upper foot pedal 52, since second connecting rod 51 connects around third Bar 53 rotates, and second connecting rod 51 at this time also corresponds to one " lever ", then under the cooperation transmission of sprocket wheel 36 and chain 4, So that first connecting rod 31 can be by downward pulling force effect, this can promote the end of wiring to be welded can be by the positive pressure of bigger Power.
4), finally start butt welding machine, the terminal portions to be welded between upper conductive column 21 and lower conductive column 22 pass through in moment Low-voltage and high-current so that the aluminium wire moment in wiring to be welded generates heat to melting and merging, in the process, due to upper conductive column 21, which can treat welding thread end, applies sufficiently large normal pressure, is equivalent to and carries out " upset " to it, this makes the position after welding High mechanical strength;Even if it is more loose that aluminium weaves cable architecture, larger normal pressure, this energy can be applied to weld in welding Enough bubbles by the welding fluid of weld squeeze out, and can also avoid the generation of clear area, significantly improve welding quality.In above-mentioned mistake Cheng Zhong is much larger than using the normal pressure that foot-treadle 52 generates and pushes the normal pressure that first connecting rod 31 generates using arm, and And it is more effortless using the force mechanism of foot-treadle 52.Under the coordinated of hand pressure device, chain 4 and foot pedal apparatus, make Obtaining the normal pressure generated using foot-treadle 52 and pushing the normal pressure that first connecting rod 31 generates using arm can be superimposed, guarantor Card weld has sufficiently large normal pressure, implementation result good in welding.Hydraulic pressure, gas relative to hydraulic cylinder, pneumatic cylinder etc The kind of drive is pressed, the structure of hand pressure device, chain 4 and foot pedal apparatus is simple, and installation cost is low, and restrictive condition is few, implementation result It is good.
Wherein, if the weld of wiring to be welded normal pressure for being subject in welding is very big, weld is easily led to Deformation is serious, is also easy to produce dimensional discrepancy.And wiring to be welded is due to specification difference, such as aluminium litzendraht wire or the single line of aluminium litzendraht wire, Its resistance to compression, bending resistance are different, it is therefore desirable to adjust the normal pressure of weld.The quantitative design of the present embodiment middle sprocket 36 is 2 A, as shown in Fig. 1 ~ 3, farther out from handle 32, second sprocket wheel 36 is relatively close from handle 32 for first sprocket wheel 36;Relative to first Chain 4 is bypassed second sprocket wheel 36, due to the difference of the arm of force by sprocket wheel 36, it is only necessary to handle 32 or foot pedal 52 apply compared with Small power can guarantee that upper conductive column 21 applies enough normal pressures to the wiring to be welded welded;Therefore, first sprocket wheel 36 and second sprocket wheel 36 is used alternatingly and hand pressure device and foot pedal apparatus alternately or are used cooperatively, so that operation becomes It is more flexible, facilitate weld job.The upper conductive column 21 and lower conductive column 22 are elliptic cylindrical shape, therefore, the upper conduction Column 21 and lower conductive column 22 disclosure satisfy that the weld job after more wiring parallel connections to be welded, that is to say, that the aluminium litzendraht wire pair Welding mechanism can disposably complete the weld job of more wiring to be welded, and welding efficiency significantly improves.
Further, for convenience of butt welding machine is started, be provided with that control butt welding machine is turned on and off on the handle 32 by Button switch 321.At this point, being also convenient for pinning button switch 321 while firmly pushing on handle 32 so that butt welding machine starts;Weldering After connecing, handle 32 and button switch 321 are unclamped.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model Protection domain within.
